Greetings,

I am running Xen-3.0.2-3, with host OS kernel version 2.6.16.13-xen0.

The system is a AMD Athlon XP running Debian/Etch.

I have 3 SATA disks plugged into a Promise TX4 SATA controller. The disks are RAIDed using Linux md with LVM wrapped around the md's for volume management.

I currently am running 3 domUs, each with LVM backed vbd's.

This server has been up for nearly a month. I am getting these types of kernel messages:

ata4: status=0x50 { DriveReady SeekComplete }
sdc: Current: sense key=0x0
   ASC=0x0 ASCQ=0x0
ata2: status=0x50 { DriveReady SeekComplete }
sdb: Current: sense key=0x0
   ASC=0x0 ASCQ=0x0
ata1: status=0x50 { DriveReady SeekComplete }
sda: Current: sense key=0x0
   ASC=0x0 ASCQ=0x0
ata4: status=0x50 { DriveReady SeekComplete }
sdc: Current: sense key=0x0
   ASC=0x0 ASCQ=0x0
ata2: status=0x50 { DriveReady SeekComplete }
sdb: Current: sense key=0x0
   ASC=0x0 ASCQ=0x0
ata1: status=0x50 { DriveReady SeekComplete }
sda: Current: sense key=0x0
   ASC=0x0 ASCQ=0x0


Basically, the messages only come up sometimes. Grepping through the logs seems to indicate that in the 28 days of uptime, these messages have been reported less than a dozen times.

There don't appear to be any symptoms, but I am thinking about taking down one of the domUs and running a fsck from within dom0 to make sure nothing bad is happening.

Anyone see this, or know anything about it?
